I looked up the flags this event (cafe35) checked, assuming your event list look like the snapshot above and can't trigger the event by simply visiting her at the cafe.
if rin_love >= 35 and library30 == True and rindorm35 == True and rininvite == True and cafe35 == False:
jump cafe35
You should've completed library30 (Under the table) and rindorm35 (Ten steps forward), so I suspect it's the rininvite flag that's obstructing. Check your
rininvite flag with URM or other save editing methods; if it's false, change it to true, and visit Rin at the cafe should do the trick.
Edit: rininvite is established during rindorm35 (Ten steps forward), where Rin would invite you on a little weekend exploration; if you're bad homie then the flag stays false, and the outing would be just Rin and Futaba, leading to event skipping.
